I'd be arriving in T1 at 12:25AM and leaving from T3 at 10:15AM. I don't have status at present, but may be able to use a lounge as guest. However, a real bed just might be better.

I requested a budget room in the Transit Hotel and they assigned me one in T1. So far so good, but the website mentions "24 hour construction" in T1.

Any recent experience on how bad the noise factor is? I would have flown ORD-NRT-SIN and would be about to fly SIN-BOM-DEL, all in Y, so a few hours decent sleep would be important.

I realize that there is some logic to T1 as I arrive there, but should I request that they switch my room to T2?

Any other tips on making the most of SIN in a few hours would also be appreciated.
